Seed 1 is just growing like crazy compared to three rest.. All ae planted in the same dirt mixture, so not sure what is causing the difference. Seed 2 and 4 are looking good, although small. Seed 3 is stunted. It is growing really slowly and something is wrong with the root. Just under the dirt, the root rapidly thins and just becomes one long thin root. Normally if water around the base of my plants, side roots will start showing. This is not the case for seed 3, i had to dig 3cm down to find the first side root. The reason I did this, even if it might not be healthy for the plant, is because it can't keep it self upright. There is to much weight already to keep it stable and I wanted to see what the problem was.
